Storm & Flood Damage Recovery in Chillum, MD

On close-set lots with shared or paved-over driveways, that surface is often the largest uninterrupted run of pavement touching the house. It collects the roof runoff of both properties and delivers it at the point where the drive meets the foundation. A shallow cross drain partway up the drive, or a regrade that throws water to the street rather than to the building, addresses more of this than anything done at the wall.

If the basement has ever backed up through a floor drain or a fixture, yes. Older inner-suburb sewers here carry more flow than they were sized for, and when a line surcharges it relieves through the lowest connected opening, which is usually a basement drain. A valve on the building sewer closes against that. It has to stay accessible and be inspected, because one that has silted open provides nothing at the moment it is needed.

In this stock, most often a window well or an areaway rather than through the foundation. Those have drains at the bottom that fill with leaves and silt over a season or two, and once blocked the well becomes a container that fills and pours through the window. Clearing those drains before the summer storm season is one of the highest-value maintenance tasks available here.
